40 years as an analog circuit designer and electronic system architect, specializing in the entertainment industry, specifically professional audio and video systems. Currently president and chief engineer of Jensen Transformers, Inc. www.jensen-transformers.com. Prior jobs with Quad-Eight Electronics (now defunct maker of large recording consoles), Laser Images, Inc. (producer of laser light show "Laserium", and Capitol Records (manager of electronic development engineering). I hold 4 patents and do a lot of technical writing and lecturing at trade shows and universities about the widely misunderstood topic of grounding and ground loops - and the problems they cause. I'm a life fellow of the Audio Engineering Society and a life senior member of the Institute of Electrical and Electronic Engineers. I live in Oxnard, CA. In my youth, I was an avid drag racing enthusiast and, with the help of my dad (a mechanic), built a modified 1955 Chevy than ran "C-gas" class and won many trophies.
